If you were walking down the street and ran into a famous person, would you ask them to take a selfie with you to prove the encounter happened?
Now what if it was Vladimir Putin?
Is there a level of reprehensibility that would cause one to ignore such an encounter?
For me the answer to the first question is "it depends," and I'm sure that's true of most people. For the second the answer is yes.
Kim Jong Un, the answer is no. He's just batshit insane. Dennis Rodman? Only if he's wearing a bridal gown at the time, or oddly, walking arm-in-arm with Mr. Kim.
